The service supports DNS over TLS, DNS over HTTPS and DNSCrypt, and provides DNSSEC validation on its resolver services. Quad9 says it does not store end-user IP addresses and operates under Swiss privacy law. Its focus is malicious-domain blocking, not content filtering; it also does not offer custom domain policies. Setup documentation covers Cloudflared, Pi-hole and open-source routers including pfSense, OPNsense, OpenWrt, MikroTik RouterOS and IPFire. Support assists with setup questions and issues. Quad9 reports 99.999% uptime for its global anycast service. The service costs nothing, with no contract or sign-up process, and is listed for Android, iOS, Linux, macOS and Windows. Large organizations planning high-volume DNS traffic are asked to contact Quad9 first.
